The Gate opens in a new, unexplored world and the Saderan Empire is at its greatest height yet. With no other rivals on the continent, they stand upon, the Saderans own and operate an empire that is unrivaled on Falmart, a power so great that the Empire has come to be associated with strength, riches, and absolute power.

And now, with the opening of the Gate to a new world, many Legions were gathered and then sent across the border to investigate this new world and to claim it as part of their growing Empire. With the expedition being led by Princess Peña and her Knights, they must now navigate the path before them.

Yet, a greater power, something so powerful and advanced, that the peasant would be forgiven for mistaking them for Gods awaits; the Kovenant Empire.
An Empire of such great power, that it can stand up to the greatest threats of its galaxy and stand as the dominant power.

Peña must now balance between her Nation and the Kovenant, as both worlds meet on a backwater Frontier Planet.
